Nigel, I meant no disrespect to your playing Rock music - it came as a surprise. You are right when it comes to certain songs written in three-chord harmony. "Cow, Cow, Boogie" comes to mind, along with many songs that singers like Dinah Washington and Billie Holiday sang and made hits with. As we know, this harmony is based on Blues. The Rock band that stands out in my mind as being one of the greatest is The Little River Band. All those guys were real musicians. Even though they had several hits in the seventies and early eighties, they received only a lukewarm reception in the United States. I never understood that. Perhaps they were too good for the "ears" that heard them.
